This is an experimental technologyBecause this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.

Note: SIMD types don't work with new, as SIMD values are no "boxed" objects (comparable to String(s) vs. new String(s), which creates a String object).

var v = new SIMD.Uint8x16(1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16);
// TypeError: SIMD.Uint8x16 is not a constructor
var w = new SIMD.Uint8x16.splat(3);
